The Youtube channels Veritasium and SmarterEveryDay recently posted an neat experiment to test the influence of the Coriolis effect on the direction of water draining down a drain (counterclockwise vs. clockwise). The Coriolis effect is the effect that a rotating body has on motion of obects on its surface. Veritasium did this experiment in Australia (34S latitude) and SmarterEveryDay did this experiment in the United States (34N latitude). The really neat part is that they designed their videos to be played together at the same time. Be sure to sync them up and enjoy!
